Combination of non-sterilized wastewater purification and high-level CO bio-capture with substantial biomass yield of an indigenous Chlorella strain.

The indigenous microalga Chlorella sorokiniana NBU-3 grown under air, 5 %, 15 %, and 25 % CO supply was evaluated to determine its potential for flue gas bio-capture, nutrient removal capacity and biomass yield using non-sterilized wastewater as growth medium. The results indicated that C. sorokiniana NBU-3 exhibited high nutrient removal efficiency (>95 % for NH-N, TN and TP) with either air or CO aeration.

[Toxic Effect of Nano-ZnO in Liver of Zebrafish].

For acute toxicity test, zebrafish were respectively exposed to the different concentrations of nano-ZnO (0, 0.05, 0.1, 5, 10, 25, 50 mg x L(-1)) for 4, 24 and 96 h.

Comparative study of pathological lesions induced by multiwalled carbon nanotubes in lungs of mice by intratracheal instillation and inhalation.

The pathological lesions induced by multiwalled carbon nanotubes (MWCNTs) in bronchi and alveoli of mice were studied by intratracheal instillation and inhalation. In instillation groups, the dose was 0.05 mg MWCNTs/mouse.
